A coupled-Bloch-mode model for explaining various optical properties of strongly modulated
subwavelength lamellar gratings is proposed. The model evidences the key role played by …

A novel polarization beam splitter using a two-layer grating coupler is proposed and
demonstrated. It can directly couple the normally incident light from fiber into two separate …

We described a highly efficient polarizing beam splitter (PBS) of a deep-etched binary-
phase fused-silica grating, where TE-and TM-polarized waves are mainly diffracted in the …

The role of multiparameter entanglement in quantum interference from collinear Type-II
spontaneous parametric down-conversion is explored using a variety of aperture shapes …

A polarization beam splitter (PBS) based on a giant-reflection to zero-order (GIRO) grating is
presented. The GIRO grating is a simple binary diffraction grating with parameters chosen …

We have measured the optical properties of wire-grid polarizers (WGPs). The implications of
these results to the application of WGPs in projectors that use reflective light valves are …

Improved diffraction efficiencies can be obtained in the paraxial domain of diffractive optics
by considering light explicitly as an electromagnetic rather than a scalar field because of the …

A novel broadband beam splitter (BS) at a wavelength of 1.55 μm is proposed and
demonstrated, which is based on the form birefringence of subwavelength binary blazed …

Here we show, analytically and numerically, that in a TiO_2 double-groove grating with two
different groove widths per period attached on the SiO_2 substrate, the normally incident …

Optical devices using double-groove diffraction gratings having periodic sets of TiO 2
elements on one or more surfaces of an SiO 2 substrate are disclosed. First order …
